Abstract
The utility model discloses an electric actuator. The electric actuator comprises a housing, wherein a motor is arranged in a cavity of the housing, a worm is connected on an output shaft of the motor, the worm is meshed with a worm gear at the upper end of the worm, an intermediate gear is fixedly connected on a worm gear shaft of the worm gear, the intermediate gear is meshed with a transmission gear at the right end of the intermediate gear, the transmission gear is connected with a power output device through a transmission shaft, and the power output device is of a cam. The electric actuator can not only do rotation motion by adopting the cam as the power output device, but also transform the rotation motion of the actuator to linear motion and realize two functions of rotation and linear motion of the actuator; and in addition, the cam is used as a power transmission deice, so that the electric actuator is soft in transmission, impact-free and small in noise.
Description
Technical field
The utility model relates to a kind of YE.
Background technology
YE is called electric operator again; It is a kind of drive unit that straight line can be provided or rotatablely move, and it utilizes certain drive energy and work under certain control signal effect.The advantage of YE is that the energy is taken conveniently, and signaling rate is fast, and long transmission distance is convenient to centralized control, and sensitivity and precision are higher, and it is convenient to cooperate with the motorized adjustment instrument, and installation connection is simple.Electric actuator for gate lock in the market is divided into rotary and plug-type two kinds, revolvingly can only play locking and unlocking function, plug-typely does electronic function of unblanking, and does not have a kind of actuator can carry out rotation and two kinds of functions of rectilinear motion.
The utility model content
The purpose of the utility model is to provide a kind of and both can carry out spinfunction to the problems referred to above, can carry out the YE of straight line push-and-pull function again.
The purpose of the utility model is to realize through following technical scheme:
A kind of YE comprises housing, is provided with motor in the chamber of said housing; Be connected with worm screw on the output shaft of said motor; Said worm screw is meshed with the worm gear of its upper end, is fixedly connected with idler gear on the worm-wheel shaft of said worm gear, and said idler gear is meshed with the travelling gear of its right-hand member; Said travelling gear is connected with PTO through power transmission shaft, and said PTO is a cam.
Special, said cam is the crescent shape structure.
Special, said motor is a reversible electric machine, it is connected with external power source through connecting plate.
The beneficial effect of the utility model is that said YE not only can rotate through adopting cam as PTO; Also can rotatablely moving of actuator be converted into rectilinear motion, realize actuator rotation and two kinds of functions of straight line, in addition; Adopt cam as power transmission; Transmission is soft, does not have bump, and noise is little.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of a kind of YE of the utility model.
Among the figure:
1, motor; 2, worm screw; 3, connecting plate; 4, worm gear; 5, idler gear; 6, cam; 7, power transmission shaft; 8, travelling gear; 9, housing.
Embodiment
Please with reference to shown in Figure 1, Fig. 1 is the structural representation of a kind of YE of the utility model.
In present embodiment, a kind of YE comprises housing 9; Be provided with motor 1 in the chamber of said housing 9, said motor 1 is a reversible electric machine, and it is connected with external power source through connecting plate 3; Be connected with worm screw 2 on the output shaft of motor 1, said worm screw 2 is meshed with the worm gear 4 of its upper end, is fixedly connected with idler gear 5 on the worm-wheel shaft of said worm gear 4; Said idler gear 5 is meshed with the travelling gear 8 of its right-hand member; Said travelling gear 8 is connected with PTO through power transmission shaft 7, and said PTO is a cam 6, and said cam 6 is the crescent shape structure.
The operation principle of the utility model is: the external control electric current gets into motor 1 through connecting plate 3, and the output shaft of motor 1 rotatablely moves under the effect of electric current and drives worm screw 2 rotations, and worm screw 2 drives worm gear 4 rotations with its engagement; Worm gear 4 drives connected idler gear 5 and rotates, and idler gear 5 drives travelling gear 8 rotations, and travelling gear 8 drives cam 6 motions through power transmission shaft 7; Because power transmission adopts cam 6 structures, it not only can rotate, and also can rotatablely moving of actuator be converted into rectilinear motion; Actuator rotation and two kinds of functions of straight line have been realized; In addition, adopt cam as power transmission, transmission is soft; Do not have bump, noise is little.
